At the moment only the one character has seen the other three rats. Lothor would certainly use a bow to target the giant rats if he is alerted to their presence. But short of that he doesn't know about them.
Also, there appear to be hundreds of rats - death by a thousand paper cuts does not sound like fun. Lothor can crush them one at a time but that doesn't do much good. Anybody have an ability to wipe out large numbers of rats at once?
Speak to animals seems like an option, but . . .
1. Probably only after the mass has been dealt with.
2. It is likely the average little critter knows nothing beyond the object of their search. The 3 big ones on the other hand might know more. The wererat theory seems reasonable.
Post Incoming.. I'm assuming that Lothor is in the same hallway as the two siblings? I'll make my post off that assumption and if it's not right i will go back in and edit where needed. I'm still not feeling 100% so this post may be not my best.
Post is up, hopefully it's okay and i didnt miss anyone as I'm unsure of who is playing which character and am too weary to actually look up the player names at the moment, but if i did miss anything, it was not my intention.
